Recent advances in synthesis of stilbene derivativesviacross-coupling reaction

Abstract

The stilbenes are undoubtedly one of the most significant moieties in various bioactive natural and synthetic structures, and they are considered as the privileged structures. Hence, preparation of such structures...

Construction of C–X (X = N, O) bonds from benzyl alcohols via Cu-BTC-catalyzed oxidative coupling

“…3), which is consistent with the reported results. 35 Based on the above experimental results and literature reports, 36 a possible reaction mechanism for the synthesis of quinazolinones and styryl ethers by oxidative coupling of benzyl alcohols to construct C-X bonds has been proposed (Fig. 4).…”

Pseudo-Stilbene- and Azobenzene-Type Systems for Optical Frequency Conversion: Estimating the First-Order Molecular Hyperpolarizability

“…From a synthetic point of view, stilbenes (-CH=CH-) are accessible via organic compound carbon-carbon coupling reactions [50]. On the other hand, pseudo-stilbenes can be prepared from the coupling of two different anilines in the case of azobenzenes (-N=N-) [51] and azo-coupling (-N=N-X-Y-), or from the condensation reaction of aldehyde and aniline in the case of azomethines (-CH=N-) [52].…”

Phthalimides: developments in synthesis and functionalization

“…For example, organocatalysis approaches are readily available, cost-effective, low toxic, environmentally friendly and insensitive to moisture or oxygen, which makes them a suitable and promising route for preparing pharmaceuticals over metal catalysts. [62][63][64][65] In 2004, Li and co-workers reported the synthesis of phthalimide 5 from the amidation of phthalic anhydride 54 by amine 10 under metal-free conditions (Scheme 34). 66 The products were obtained in excellent yields with a trace amount of the uncyclized byproduct 55.…”
